When laboratory data or actual water samples are unavailable, the density of formation water at reservoir conditions can be estimated roughly (usually to within +/−10%) from correlations ( Figs. Experimental verification of the computer predictions should be performed in cases in which any error could have significant impact. Alternatively, some modern multicomponent chemical equilibrium simulators accurately calculate the densities (and other physical properties) from the complete analysis of the waters within the temperature and pressure range of the thermodynamic database. Thus, water samples taken for providing input to these programs must have accurate densities determined experimentally. However, process simulation software used in modern facility design uses the true density or specific gravity of the water to avoid significant cumulative errors, especially when working with low-gravity heavy oils or concentrated brines. Quantity in kg= quantity in gallons * 3.In the past, density in metric units (g/cm 3) was considered equal to specific gravity therefore, for most engineering calculations, density and specific gravity were interchangeable in most of the older designs. This conversion is from a unit of volume to weight, and so density is crucial to solving it: You can use the formula to convert any quantity from kilograms to gallons as long as you know its density in g/ml. If you place it in the formula along with 9.5 kg, your result is 2.85 gallons. For example, you want to convert 9.5 kg of cooking oil to gallons, the vital thing to know is the density of oil is 0.88 g/ml. Quantity in gallons = quantity in kg / (3.785412 * density) To convert a quantity from kg to gallons, use the following, more detailed, formula: You can convert any value you wish from kilograms to gallons, and vice versa - just follow the steps given below: For UK gallon, the ratio is a little bit different: This ratio is valid for water and quantities with a density equal to water, i.e., 1 g/ml. The ratio of a kilogram, kg, to a US gallon, gal, for water is: Our kg to gallons calculator converts quantities both ways, i.e., from kg to gallons and from gallons to kg. In the metric system, kilogram is the unit of weight, while in the imperial system, the unit of volume is gallons.Ī gallon is equal to 4 quarts, 8 pints, or 16 cups. Just to let you know, we have a gallons to pounds calculator as well, if you are curious.
